Introducing Service Broker for Kubernetes

David Cabelus
Senior Principal Product Manager

We are pleased to announce the general availability of Oracle Cloud Infrastructure Service Broker for Kubernetes. With the continued adoption of DevOps and Kubernetes, developers want to streamline their automated deployment strategies to include provisioning and binding to any cloud service on which their application or microservice depends. For example, if your application depends on object storage wherever the application is running, then provisioning storage buckets should be part of the deployment process for the application. Better yet, it should be part of the deployment process within Kubernetes. 

This notion of simplified and combined deployment is what spawned the Open Service Broker API project, which provides a consistent model for exposing cloud services to applications and application deployment tooling. The new service broker is an implementation of the Open Service Broker API for use in a Kubernetes cluster and for use with Oracle Cloud Infrastructure services. It simplifies access to Oracle Cloud Infrastructure services, including new services like our Autonomous Databases, which can be a highly scalable, automated, self-tuning backend for microservices and containerized applications.

How Service Broker Works

Oracle Cloud Infrastructure Service Broker for Kubernetes is available as a Helm chart, a Docker container, and in open source. It includes service broker adapters for the following services (with more to come):

  • Autonomous Transaction Processing
  • Autonomous Data Warehouse
  • Object Storage
  • Streaming

You can add the service broker to your Kubernetes cluster, and then use the Open Service Broker APIs from within kubectl to interact with the preceding cloud services. You don't need to provision these services before you deploy your application, or remember to clean them up after you un-deploy the application.

Service brokers enable application portability, too. The combination of a consistent model and embedding cloud service provisioning within your application deployment process means that when you deploy your application in a new cloud environment, it has everything that it needs to run. This is true for dev-test-production progressions, and for on-premises-to-cloud migrations.

To further enable application portability, a service broker can also be used to create service bindings to cloud services. For each binding, the service broker creates a Kubernetes secret that contains necessary information to connect to the service. Contents and format vary. For example, a binding to the Object Storage service can contain a pre-authenticated URI to access the storage bucket.
